Measles
Urgent
Measles is a highly contagious viral infection that commonly causes fever, cough, runny nose, red or watery eyes, and a characteristic widespread rash. The illness can cause complications involving the lungs, ears, brain, or other organs, particularly in young children and people with weakened immunity. Measles spreads readily through respiratory particles and can remain infectious in indoor environments after an infected person has left. Vaccination provides highly effective protection.

When to Seek Medical Attention
Measles requires medical assessment because complications can include pneumonia and inflammation of the brain. Seek prompt medical care for suspected measles, particularly in infants, pregnant people, or those with weakened immune systems. Emergency assessment is needed for severe breathing difficulty, dehydration, seizures, confusion, unusual sleepiness, severe headache, or other signs of serious complications.

Overview
Measles is a highly contagious viral infection that commonly causes fever, cough, runny nose, red or watery eyes, and a characteristic widespread rash.

Causes 1
Measles is caused by the measles virus, which spreads primarily through respiratory particles from infected people. The virus enters the respiratory tract and replicates before spreading through the body. It can cause widespread immune and inflammatory effects that produce the characteristic fever and rash. Because the virus is highly contagious, infection can spread rapidly among people who are not immune. Infection usually results in long-lasting immunity after recovery.
Infection
Risk Factors
The greatest risk is lack of immunity to measles. Unvaccinated or incompletely vaccinated people are vulnerable to infection when exposed. Risk of severe complications is higher among young children, pregnant people, adults with certain health conditions, and people with weakened immune systems. International travel or exposure during outbreaks can increase the likelihood of encountering the virus. High population immunity substantially limits transmission and outbreaks.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Measles is suspected when a person has fever and the characteristic respiratory symptoms followed by a widespread rash, particularly when there has been a known exposure or inadequate immunity. Laboratory testing is used to confirm many suspected cases, often with molecular testing or serologic methods. Because measles is highly contagious, suspected cases may require prompt public health notification and appropriate infection-control measures while diagnostic evaluation is completed.
Prevention
Key Prevention Tips
Vaccination is the most effective way to prevent measles
Maintaining recommended vaccination according to the local immunization schedule helps protect both individuals and communities
During outbreaks or after significant exposure, public health authorities may recommend additional measures for susceptible people
Good respiratory hygiene and avoiding close contact with infected individuals can reduce transmission, although vaccination provides much stronger protection than these measures alone
Prevention Guidance
Vaccination is the most effective way to prevent measles. Maintaining recommended vaccination according to the local immunization schedule helps protect both individuals and communities. During outbreaks or after significant exposure, public health authorities may recommend additional measures for susceptible people. Good respiratory hygiene and avoiding close contact with infected individuals can reduce transmission, although vaccination provides much stronger protection than these measures alone.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
